Forces between circular magnetic hole defects and vortex cores in antiferromagnetic nanodisks
Abstract
The presence of defects or impurities in ferromagnetic nanodisks may profoundly affect the structure and dynamics of stable vortex-like magnetization. Here, we use Monte Carlo and spin dynamics techniques for investigating how a minor defect like a magnetic dot interacts with the antiferromagnetic (AFM) vortex core. We have found that an individual ferromagnetic (antiferromagnetic) circular defect induces a potential that attracts (repels) the AFM vortex core.
